ACHIEVEMENT-RELATED EXPECTANCIES, ACADEMIC SELF-CONCEPT, AND MATHEMATICS PERFORMANCE OF ACADEMICALLY UNDERPREPARED ADOLESCENT STUDENTS

The relationship between achievement-related expectancies, academic self-concept, and mathematics performance of 191 academically underprepared adolescent students was examined. After the effects of prior academic achievement were controlled for, a significant main effect for academic self-concept was found, as expected, students with higher academic self-concept earned significantly hi-her mathematics grades. In addition, after the effects of prior achievement were controlled for, female students were found to cam significantly higher mathematics grades than did male students. A significant three-way (Sex x Ethnic Group x Achievement-Related Expectancies) interaction was also noted. Unlike in several previous studies, no significant racial differences in mathematics performance were found. These students had a similar socioeconomic status (SES), and the effects of prior academic achievement were controlled for, suggesting that racial and gender differences in mathematics achievement may be partially explained by prior schooling and SES background, as posited by Reyes and Stanic (1988).
